Kurzbeschreibung
Ethernet technology is used in the LAN to perform the functions of connection and transmission. The WiFi technology allows a radio access to the LAN. The WAN is built in three parts : the access network, the aggregation network and the core network. The access network implements xDSL and EFM technology. The aggregation network uses an evolution of Ethernet technology to suit the constraints of the operators. The core network implements MPLS to provide VPN service level 2 or level 3. It is also making a presentation of multicast flow control.
This book summarizes the key Quality of Service technologies deployed in telecommunications networks: Ethernet, IP, and MPLS. The QoS of the network is made up of two parts: fault and resource management.
Network operation quality is among the functions to be fulfilled in order to offer QoS to the end user. It is characterized by four parameters: packet loss, delay, jitter or the variation of delay over time, and availability. Resource management employs mechanisms that enable the first three parameters to be guaranteed or optimized. Fault management aims to ensure continuity of service.
